Answer this question truthfully
### Question: What to expect if I have Alzheimer%27s disease  (Outlook/Prognosis)?
### Response: The trajectory of AD is different for each person. If AD develops quickly, it is more likely to worsen quickly. Patients with AD often die earlier than normal, although a patient may live anywhere from 3 to 20 years after being diagnosed. The final phase of the disease may last from a few months to several years. During that time, the patient becomes immobile and totally disabled. Death usually occurs from an infection or a failure of other body systems.
